Water resources development and management

This paper examines the maximum available water resources in Japan, nationally and by region, and describes the present balance of demand and supply. The major existing mechanisms of water development and control ‐ dam construction and pricing structures ‐ are reviewed. Finally a classification of various stages of water resource and irrigation development is presented. These stages are identified as reliance on natural river discharge, the construction of reservoirs, restrictions on water use, inter‐basin planning, and the construction of reservoirs for perennial water regulation.
